Application filed April 5, 1888, Serial No. 269,688. (No model.)

To aZZ whom it may concern.-

Beitknown that I, JOHN S. LANG, a citizenof the United States, residing at Ypsilanti, county of Washtenau, State of Michigan, have inventeda certain new and useful Improvement in Tire-Bolt Wrenches; and I declare the following to be a full, clear, and exact descrip tion of the same, such as will enable others skilled in the artto which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

In the drawings, Figure l is a view of my tire-bolt wrench. Fig. 2 shows the same in use upon a wheel. Fig. 3 shows a variation in the form of the frame.

It is the purpose of my invention to produce a convenient wrench for the purpose of running the nuts onto or off from tire-bolts.

instrument by the employment of wrench heads of various sizes to suit all the different sizes of tire-bolts and nuts.

B is'a bevel-gear engaged with a drivinggear, B on the shaft B, and a crank, B is provided with which to operate the device. A is a cross arm, which, for carriagewrenches, may be provided with a lining of rubber, leather, or other cushion to prevent damage to the paint or finish of the wheel.

The crossarm A is designed to rest upon the spokes to steady the tool and to permit it to project down between the spokes in proper place to engage the nuts.

a represents a nut or any other suitable de- It is apparent that with this device the operator may put his wrench on the nut andthe crossbar A against the spokes. He may then bear strongly with it against the spokes, and so hold the tool steadily to its work while he turns the crank.

What I claim is- 1. A tire-bolt wrench consisting of a shaft provided with a wrenehhead at its end, and in connection therewith gear-wheels and a crank, whereby said wrench may be operated, and a cross-arm adapted to rest upon the spokes of the wheel, substantially as and for the purpose described.

2. A tire-bolt wrench consisting of the combination, with the wrench, its shaft, and connecting-gears, of a cross-arn1 arranged in a plane above the level of the wrench-shaft, and adapted when resting upon the spokes to properly locate and support the wrench in position for its work, substantially as described.

3. The tire-bolt wrench consisting ofa frame provided with shafts B and B engaged by gears, a crank, 13, a cross-bar, A, and a removable wreneh-head, B, substantially as and for the purposes described.

In testimony whereofIsignthisspecilication in the presence of two witnesses.
